Well before hunting season I would suggest you do some testing starting with the load recommended above. Minie's IMO are the way to go and you can vary the powder charge until you're right on at 100 yds. with one of the sight settings.
At that point you should be good to go for a primative weapons hunt. Good Luck!
BTW: Did you pass your Spanish class?
